Three-Month Assessment of Histological Data from Each Replicate Sample

	Tissue ingrowth and continuity (H&E)	Myelinated fibers (LFB)	Astrocyte immigration (GFAP)	Axonal infiltration (Tuj1)
Cylinder (n = 3)	−	−	−	−
Tube (n = 3)	+	−	−	+
Channel (n = 3)	+	−	+	+
Open-path without core (n = 3)	+ +	+ +	+	+ +
Open-path with core (n = 3)	+ +	+ + +	+ +	+ + +

Presence of staining or labeling within the defect site in one or more section of each replicate is indicated by a (+) for each replicate animal, whereas a (−) indicates none found. In the case of tissue ingrowth and continuity, fibrous tissue continuity between stumps and scaffold on both ends was assigned a (+), whereas discontinuity in all groups received a (−).
